[otrs] LDAP Binding Issue

13 Feb 2009

      Hi all,

I'm trying to setup OTRS to authenticate agent logins with AD.  Here is
a clip from my Config.pm:

    # -----------------------------------------------------#
    # ldap settings                                        #
    # -----------------------------------------------------#

    $Self->{'AuthModule'} = 'Kernel::System::Auth::LDAP';
    $Self->{'AuthModule::LDAP::Host'} = '10.67.100.5';
    $Self->{'AuthModule::LDAP::BaseDN'} = 'dc=towtradtal,dc=com';
    $Self->{'AuthModule::LDAP::UID'} = 'sAMAccountName';
    $Self->{'AuthModule::LDAP::SearchUserDN'} = 'CN=otrsLDAP,OU=Service
Accounts,OU=Users,OU=Chicago,DC=towtradtal,DC=com';
    $Self->{'AuthModule::LDAP::SearchUserPW'} = '*********';
    $Self->{'AuthModule::LDAP::GroupDN'} = 'CN=Domain
Users,CN=Builtin,DC=towtradtal,DC=com';
    $Self->{'AuthModule::LDAP::UserAttr'} = 'DN';
    $Self->{'AuthModule::LDAP::AccessAttr'} = 'member';

    $Self->{'AuthModule::LDAP::Params'} = {
       port => 389,
       timeout => 120,
       async => 0,
       version => 3,
    };

In following the OTRS documentation as well as cross-referencing other
posts on this subject, I'm pretty sure the config file is setup
correctly and does not include any syntax errors.  However, my problem
is that when logging in to OTRS, I get "Login Failed! Your username and
password was entered incorrectly."  I then checked the apache logs and
found the following entry:

ERROR: OTRS-CGI-10 Perl: 5.10.0 OS: linux Time: Fri Feb 13 12:36:59 2009

 Message: Search failed! 00000000: LdapErr: DSID-0C090627, comment: In

the connection., data 0, vece

 Traceback (4362):

I've verified that the credentials I have specified for the user
otrsLDAP are correct by binding to AD through LDP.exe.  I'd really
appreciate if someone could let me know if they'd run into this or know
what might be causing the bind to fail.
